TO ALL WHOM IT MAY CONCERN;

Be it known'thzit we, JOHN G. MnTTINeLY and BENJAMIN F. MA'rrINcLY, of the city of Louisville, county of-Jeiferson, andState of Kentucky, have invented a new and useful Improvement in Boilers for the Purpose of Distilling Whiskey or other'Spirits, entitled John-G. and Benjamin F. Mattingly's water-jacket stillboiler, for the purpose of preventing the beer from burning or encrusting on the bottom of'the boiler, whilein.

the process of distillation; and we do hereby declare that the following is a full, clear, and exact description I of the construction and operation of theiabove-name dboiler, as will be seen by reference to the annexed drawings,'and to the letters-of reference marked thereon, to wit:

Figure 1 represents a'perspective view of the boiler, with the side out out, so as to expose to view all the inside of the boiler, including the flues, water-space of water-jacket, and the space around the ilues occupied by the beer.

4 A is the boiler, inside of the water-jacket. i

B is the openings through the flucs, through which the fire and smoke pass, running parallel through the boiler, in the same manner as thatof any ordinary steam-boiler.

C is the space in the boiler occupied by the beer around the flues.

p D is the space for wateriin the water-jacket, which surrounds the boiler, and is kept constantly about two thirds full of water, when in operation, and any steam generated from this water, escapes throughthe pipe E, on the-top ofthe boiler, and is used for the purpose of distilling water, and other purposes; and the above water-jacket is supplied with water through the pipe F, in the front end of the boiler.

G is the waste-pipe, in the bottom ofthe boiler, for the purpose of drawing of? the beer when the spirit has all been extracted. 7 i I H is the opening in the top of the boiler, for the purpose of filling the boiler with the beer, after which it is closed up by the ordinary still-head, which connects with the other necessary fixtures used in distilling.

The above is a full description of theboiler referred to, and is made of copper, in the usual way, and is surrounded by a cylinder, made of iron, about tlii-ce-sixtecntlis of an inch in thickness, andiabout eight inches larger in diameter than the boiler, and is riveted fast to a flancli of the head of tho'boiler, so as to be watertight, and when so done, it leaves a water-space of about four inches all around the boiler, which is filled about two-thirds full of water, and hence is calledthe water-jacket, which extends from end to end of the boiler; and in order to operate said boiler, it is only necessary to have it set up, in the usual'way of setting steam-boilers, and after-which it is filled with the beer, and enclosed with the ordinary still-head, and after filling the waterjacket with water, a fire is made in the furnace under the boiler, and the heat of which passes through the flues, and causes the water and beer to boil, and hence the spirit is extracted therefrom.

Now, therefore, we do not claim anything as'original in the construction of the above boiler, but

What we do claim as our invention or improvement, and desire to secure by Letters Patent, is-

The water-jacket, and the use of water around the boiler in order to prevent the beer from burning or encrusting on the bottom oi the boiler, when used for distilling purposes, when arranged, constructed, and

operating asset forth.
